To a?! whom 225 may concern:

Be it known that I, IGNAZ E'rmcn, a subject of the Emperor of Austria-I'hmgary, residing at Oberaltstadt, near 'lrautcnau, Bohemia, Austria-I-Iungarv, have invented certain new and useful mprovements in DrivingDevices for the Spindles of Spinning-Machines, of which the following is a specification.

.With the known spindle constructions, the spindles of spinning machines or their hecks are rotated by'means of the cord'whirl which connects a cord pulley driven by and situated on the main shaft of the spinning machine with the driving whirl on thespindleor heck. "A separate whirl cord is generally provided for each spindleof aibank and all cords are driven in common by the drivin oord pulley .(drum), which is' arrange d bn the main driving shaft For spinmng PIIIILOSQSflllS method of'drlving lS accompanied y disadvantages, inasmuch as all the whirl cords are" not equally stretched and these disadvantages still further in-,.

crease during the working to the disadvantage of the spinning process. The unequal tension of the cords of the whirl results in the various spindles of the same bank not rotating at the same speed and it is impos-.

sible to prevent a slackening of the speed of the various spindles more particularly during the working.

The present invention refers to a driving device for the spindles of spinning machines,

which does away with the above mentioned disadvantages and permits of exactly regulating the tension of the cord of the whirl for each spindle, especially during the working. With this ob ect in view according to the present invention a special tensioning device in the form of an adjustable lever is provided for the whirl cord of each spindle, which lever permits of equalizing the tension in the various cords, and in a slackening of the tension, the tension of each separate cord can be brought up to the exact degree necessary for obtaining a perfect spinning rocess.

I s all now describe my invention with reference to the accompanying drawing showing one form of constructionof the present invention, in which,-Figure 1, is a side elevation partly in section, Fig. 2, is a front elevation.

For the form of construction shown as example a spindle having a bell-shaped heck a has been chosen, within which the spindle 6 formed as tube for receiving the lubricantcan freely rotate, and which by means of the driving whirl 0 fixed on the fly a is caused to rotate. An arm a is provided on the spindle beam (Z and carries a pivoting arm {1 adjustable as regards its inclination by means of a manually operable set-screw f. A groove-pulley or roller It, is provided at the upper end of the arm 7 and around which the cord 2' coming from the driving pulley and looped'around the driving whirl c is conducted back directly to the driving ,pulley. As the driving whirl is driven and completely surrounded by the tensioned side of the driving cord, so any lateral strain on the bearing is avoided, thus permittin a very easy driving, the bell-shaped heat a acting like a free-wheel. By the adjustment of the arm g, through set-screw f which is situated so as to be conveniently actuated by the worker, the tension of the whirl cord may be varied and as a similar arrangement is provided for every spindle, each spindle of the bank can be separately regulated. The roller 72, is arranged on the upper end of the arm 9 pivoting on a-special support and can be fixed at various inclinations by .means-of the manually operable set-screw Z. -By the adjustment of the support-7:, the rollerh can be exactly adjusted corresponding to the direct-ion of the tension of the cord. If the tension in one of the whirl cords has slackened so that there is danger of the spindle in question soon turning at a reduced speed, then it will only be necessary to manually turn the set-screw f thereby maintaining the necessary tension in the whirl cord. Owing to the altered position of the arm g resulting from this adjustment, the position of the roller It will also be varied so that in order to obtain a uniform runnin on and running oft of the cord 2', the rol er It can be adjusted by means of manually operating the set-screw Z. By means of this adjustment of the various stretching of the rollers of the spindles of a bank, a uniform tensioning oil all the whirl cords is obtained, so that the speed of the various spindles and hecks is maintained at the required degree, thus favorably affecting the spinning process and furthermore resulting in considerable economy in the use of cords.

The above described arrangement can also be ap lied with spindles of other construction, or example with all those spindles in which the spindles themselves or the heclts are driven by a whirl cord.

. to and from said spindle member, a set screw for actuating said arm to an adjusted position, a second arm pivoted to the free end of said first mentioned arm, a pulley carried by said second mentioned arm and adapted to receive said flexible drive, the plane of movement of said second mentioned arm being substantially in the line of tension of said drive, and means for actuating said second mentioned lever for positioning said pulley relative to the direction of tension of the said drive.

2-. In a spinning apparatus, the combination with a remluble mounted spindle mem ber, provided with a flexible drive, of means for independently adjusting the tension of said flexible drive, in coiipe-ration with said spindle member, such means including a pulley about which said flexible drive isv trained, a device movable to and from said spindle member in the line of tension of said drive, a support for said pulley pivotally carried by said device, and manually operable means for actuating said support to rigidly position said pulley relative to the direction of tension of said drive.

3. In a spinning apparatus, the combination with a revolubly mounted spindle member provided with a flexible drive, of mecha- 4o nism movable toward or from said spindle member at the opposite side thereof from the source of power of the flexible drive, manually operable means for actuating and rigidly retaining the mechanism againsttension of said flexible member, and a pulley carried by said mechanism about. which the flexible d rive is trained, substantially as and for the purpose set forth.
